No I have absolutely no problem...I would like you to ask questions as I said even I get a chance to learn this way

You can try through DHCP

no need to put an additional entry of peerdns

Just follow other steps and let me know the results.

yes i am using DHCP instead of static ip addresses....and i want to continue that way..

that means which step should i follow??the first one or the second one,i didn't understand your answers clearly,please don't mind and thanks once again....you are really helping me..

And can you please tell me whose ip address should i be giving in vi /etc/hosts?is it the machine ip or the nameservers ip?and what does the hostname mean here,if it"s the DNS server name which comes in the machine then for me it is localhost.localdomain...is this the right one?or is it the address for the nameservers?

And whose address should i be giving in /etc/resolv.conf directory....i have 2 nameservers,should i be giving both?or do i have to give both the nameservers ip and then machine ip?

please ur help will be highly appreciated...

See if you are want to configure a DNS server then it is always better to use a static IP because in this way you can reserve the IP for DNS server but instead if you are using DHCP then there are chances that IP goes to someone else in you network which will lead to problems.

As I had tried with a static IP

But still if you want to continue with DHCP then

Code:

#ifconfig
for now let me take your machine's IP as 192.168.0.100
and your hostname localhost.localdomain.com

will show you your current IP address

This is the address which you will use in

Code:

/etc/resolv.conf
nameserver 192.168.0.100
nameserver (your primary DNS)
nameserver (your secondary DNS)

See the basic idea of using your IP in resolv.conf is because you are creating a local domain name which is not registered on internet so the DNS server which you are using will not recognize the domain name server which you are planning to create

So you need to assign your machines IP in resolv.conf to remove name resolution issue

So in the first option mention your machine's IP then the DNS servers which you are using as second and third option

In

Code:

/etc/hosts

192.168.0.100 localhost.localdomain.com

Same IP is to be used in /etc/hosts and /etc/resolv.conf
